On 12 February, Mexican Indigenous human rights defenders, Obtilia Eugenio Manuel and Hilario Cornelio Castro disappeared while traveling through Guerrero state, southwest Mexico. They were both members of the Organization of Indigenous Mepha'a People (OPIM, Organización del Pueblo Indígena Mepha'a). Since 2009, due to their human rights work, Obtilia Eugenio and other OPIM members have received several attacks and threats, including death threats. Obtilia Eugenio was recently elected member of the Indigenous Municipal Council of the Ayutla de los Libres town (Guerrero state). Their fate or whereabouts are unknown. Authorities must urgently search for them and bring those responsible to justice.
